Translate components:
- BulkReplaceModal: add dictionary selection dropdown to save replacements
directly to a dictionary after applying bulk find-replace
- CorrectionCell: improve inline edit UX with better state handling
- TermCorrectionPopup: enhanced popup for term corrections
- ConfigTabForm: update form field bindings
- RunTabContent: minor layout adjustments
- ScheduleConfig: improved schedule configuration UI
- TranslationPreview, TranslationRunGlobalIndicator, TranslationRunProgress:
UX polish and state management improvements
BackupManager:
- Add AbortSignal.timeout(30s) to prevent infinite loading state
- Add onDestroy AbortController cleanup to prevent stale state
- Add error toasts for failure states (was missing — state hung forever)
- Import API_REQUEST_TIMEOUT from api.ts
- Add composite index ix_translation_records_run_source_hash
for NOT EXISTS dedup subquery performance + Alembic migration
- Remove duplicate #endregion in orchestrator.py (INV_3)
- Replace hardcoded RU fallback 'Статус' with 'Status'
- Add early return guard to loadMoreRecords()
- Show records summary always when recordsTotal > 0
Backend:
- deduplicate param in GET /runs/{id}/records — NOT EXISTS subquery
with (created_at, id) tiebreaker for one row per source_hash
- source_data and source_hash added to records JSON response
- fix missing status import in _run_history_routes.py (NameError)
- fix tab/space mixup in orchestrator_aggregator.py
- remove duplicated @RELATION edges in metrics.py
- fix #region/#endregion style and @PURPOSE→@BRIEF in metrics.py
Frontend:
- RunTabContent: summary metrics bar (fetchJobMetrics) with HelpTooltips
- RunTabContent: trigger_type badge, duration, cache rate in run rows
- TranslationRunResult: deduplicate=true by default, paginated Load more
- TranslationRunResult: per-language token_count and estimated_cost
- TranslationRunResult: collapsible batch breakdown with timing
- TranslationRunResult: Bulk Replace button in header and records table
- TranslationRunResult: source_data key values shown under source text
i18n: all new keys in EN + RU (load_more_records, showing_records,
sum_*, help_sum_*, trigger_*, batch_*, duration_label, cost_label,
cache_rate, load_more_records)
- PolicyForm.svelte: replaced raw inputs/selects/buttons with /ui atoms
(Button, Input, Select), added i18n for all labels and messages
- Automation page: replaced manual layout with PageHeader/Card/EmptyState
atoms, added i18n everywhere, stripped debug logging
- Added i18n keys for en/ru (settings: 45 new keys, validation: 1 new key)
- Fixed validation new page description to use dedicated i18n key
Root cause: onchange on native <select> passes a DOM Event.
The parent handler used e.detail, which is always 0 for native events.
Sequence:
1. bind:value sets environmentId correctly
2. onchange fires -> handleEnvChange(0) overwrites to falsy
3. <select> re-renders showing 'Select environment...'
Fix:
- ConfigTabForm: onchange now passes e.target.value (the actual envId)
- +page.svelte: callback receives the envId string directly, not e.detail
@RATIONALE bind:value on <select> fires on the same change event.
The handler must not re-set the same bindable to a stale value.
Verification: browser reconfirmed — ss-dev stays selected after click.
Svelte 5 compiler fails to detect Proxy-based i18n store `t` as a store
in deeply nested/complex templates and in `.svelte.ts` model files,
generating `ReferenceError: $t is not defined` at runtime.
Fix: replace `$t.` references with:
- Template: `_t.` where `const _t = $derived(getT())`
- Script: `getT()?.` direct function call
Applied to:
- translate/[id]/+page.svelte (the failing page)
- TranslationJobModel.svelte.ts ($derived.by() in `tabs`)
- 12 translate components (ConfigTabForm, ScheduleConfig,
TranslationPreview, TargetTabForm, RunTabContent, BulkReplaceModal,
TranslationRunProgress, TranslationRunResult, TermCorrectionPopup,
BulkCorrectionSidebar, TranslationMetricsDashboard, CorrectionCell,
TranslationRunGlobalIndicator)
Verified all 5 tabs render correctly in browser:
Config, Preview, Target, Run, Schedule.
Build clean, 698/698 tests pass, 0 color violations.
Backend:
- TranslationRun model: add cache_hits Integer column (default 0)
- TranslationRunResponse schema: add cache_hits field
- _helpers.py/_run_list_routes.py/orchestrator_aggregator.py: include
cache_hits in all run API responses
- _batch_proc.py: count pre_rows served from translation cache per
batch, return cache_hits in batch result
- executor.py: accumulate cache_hits across batches, persist to run
- Alembic migration: dabc9709 — add cache_hits column to translation_runs
Frontend:
- translationRun.svelte.ts: add cacheHits to store state, WS handler,
polling handler
- TranslationRunProgress.svelte: 5-col stats grid with purple Cache card
- TranslationRunGlobalIndicator.svelte: 5-col stats with Cache
- TranslationRunResult.svelte: 5-col detail stats with Cache card
- History page: cache_hits shown in run list row + detail panel
Visual: cache hits shown in purple alongside green/yellow/red metrics
(total/success/failed/skipped). Visible during run + in history.
Tests: backend 69/69 translate tests ✅, frontend 698/698 tests ✅,
frontend build ✅
Fixes:
- Move batch size, upsert strategy, include source reference
from Config tab to Target Config tab (Write Settings section)
- Fix 'Dataset #26' fallback — look up real datasource name
via API when source_table is not saved in job data
- Persist include_source_reference in save payload and
restore from job data on load (was a pre-existing gap)
QA review fixes:
- Update @BRIEF contracts for both tabs
- Fix import indentation in +page.svelte
Other: help tooltips on translate pages, flow hint on list page,
git migration manager components, dashboard hub pages,
migration settings pages
1. Remove get_config_manager() call from translate_run_websocket
(@app.websocket /ws/translate/run/{run_id}) — was not imported
and unused. Also remove unused from sqlalchemy.orm import Session.
2. Fix prop name mismatch: showBulkReplace -> showPageBulkReplace
in RunTabContent. Use () for reactive two-way binding.
3. Add ('DRAFT') for status prop in RunTabContent.
Remove loadColumnsForDatasource, searchDatasources, selectDatasource,
toggleContextColumn, toggleSourceKeyCol, updateTargetKeyCol, isVirtual
from page — all moved to ConfigTabForm.svelte.
Add on datasourceId in ConfigTabForm to auto-load columns
when parent sets datasourceId (loadJob) or user selects a datasource.
Introduce a centralized tool registry system for the assistant to manage
executable operations, permissions, and tool catalogs. This refactors
the assistant dispatch logic from a monolithic approach to a modular,
decorator-based registry.
Key changes:
- Implement `AssistantToolRegistry` to handle tool registration,
permission checks, and safe operation identification.
- Add a suite of new assistant tools: backup, commit, branch creation,
deployment, health summary, environment listing, LLM operations,
maintenance, migration, and dashboard searching.
- Refactor `_dispatch.py` and `_llm_planner.py` to utilize the new
registry for intent resolution and tool catalog building.
- Enhance the LLM planner to support more descriptive clarification
responses in Russian when intents are ambiguous.
- Update the frontend to support the new tool-based workflow, including
improved i18n labels for assistant operations and a new step-by-step
wizard for the migration page.
- Add ADR-0008 to document the architectural decision for the tool
registry.
Introduce a new API key authentication mechanism to support service-to-service
communication (e.g., Airflow, CI/CD) without browser-based JWT login.
- Add `APIKey` model and `APIKeyPrincipal` dependency for RBAC.
- Implement `require_api_key_or_jwt` dependency with environment scoping.
- Add admin CRUD endpoints for API key lifecycle management.
- Add API key management UI in System Settings.
- Update maintenance API to support explicit `environment_id` and API key auth.
- Add i18n support for API keys and connection settings.
- Include Python and Bash usage examples in the `examples/` directory.
- Update technical specifications and documentation.
- Add ondelete=CASCADE/SET NULL to all environment and translate FK constraints
- Add is_multimodal to GET /api/settings/consolidated response
- Fix toggleActive to not overwrite is_multimodal with false
- New SearchableMultiSelect component for dashboard search with multi-select
- Fix validation task page: task data unwrapping, date formatting, dashboard multi-select
- Fix infinite effect loop on dashboards page via queueMicrotask guard
- 3 new Alembic migrations (merge f0e9d8c7b6a5, translate b0c1d2e3f4a5)
Backend:
- /api/validation/ CRUD for validation tasks (policies)
- Run history with 6 filters + pagination
- Alembic migrations (provider_id, policy_id)
- 28 pytest tests
Frontend:
- /validation — task list page with status filters + CRUD
- /validation/[id] — task config (Config + History tabs)
- /validation/history — run history with metrics
- Sidebar nav entry under Operations
- i18n en/ru
Playwright (ScreenshotService):
- Removed 25s hardcoded sleeps → conditional waits
- CDP fallback to full_page screenshot
- Total timeout enforcement (120s)
- Debug screenshots → temp dir with cleanup
QA fixes:
- Debug screenshot accumulation in production (tempdir + rmtree)
- Frontend API payload field name mismatch
- History issues field reference fix
- delete_runs scoped by policy_id
Belief protocol:
- @RATIONALE/@REJECTED on 27 C4+ contracts
